hi all, thinking of putting moisture traps in caravan , how many in a 21ft interior , where to put them , how often do they need empting ,will the crsytals/chemicals cause any damage....pete
moisture trap

Suggest 3 ,empty down outside drain,empty when about inch of water is in them so you do not spill whilst taking them outside.Refill when they are almost evaporated. Have found them excellent.
You will always have water in these traps as your van is not airtight, therefore you are effectively absorbing moisture from the outside...a never ending job?

I agree with Ron you simply collect all the external moisture so it is a pointless exercise,better to put the fire on every now and again on electric if possible.
Yes agree it would be a never ending job. It should not be necessary to use such a thing in a van if it is not experiencing damp problems in the first place. In fact using such things will even encourage more damp air into the van to a point where the air inside the van is damper than the air outside. Give them a miss is the best bet.
As it was me suggesting having 3 ,it was a couple of years ago that i done my useual damp test and all was ok so just wondered if cushions etc were damp and not just cold and found they were all absorbing moisture.I then put 2 in the front and 1 in rear bathroom.some time afterwards i checked and found not only the moisture had fallen and all fabric had that feel of dryness.For the whole winter period i used 1 bag which came to
I seem to recall that when butane/propane burns it produces water this may however all end up the flue not sure also leaving a van unattended with a 'flame' in it could be an issue if it caught fire the insurance may use it as a get out.
Hi Plotter
Yes you are correct, when ever a flame burns it does produce water vapour as one of the products of combustion.
Most importantly all gas fires that are currently fitted to caravans must be room sealed. The room seal does ensure that all product of combustion are kept out of the living space by virtue of the flue. So only warm dry air I produced inside the living space. To that extent it is no different to an electric heater.
I agree there would be an issue about leaving gas burning in caravan whist on a storage site, not least the fact that it will eventually run out. Where as electric power is easily controlled on a thermostat and generally speaking it will reset after a power cut.
The risk of a gas fire actually causing a caravan fire is very low provided the heater has been installed and serviced properly. But equally electrical heaters can malfunction and cause fires, so there is probably some bylaw on most storage sites about electric appliances also.
For use when on holiday gas is a good and safe solution.
